LM317T-HXY from HXY MOSFET, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ADJ | passive | Adjust pin; sets the output voltage (1.2V to 37V range) via external resistor divider, with adjustment pin current Iq max 100 μA. |
| 2 | OUTPUT | power_out | Regulated output terminal supplying output current in excess of 1.5A (rated 1.5A) over a 1.2V to 37V output range. |
| 3 | INPUT | power_in | Unregulated input terminal with maximum input voltage rating of 40V. |
